Struct Context 

pub struct Context {
    pub key_mods: KeyboardModifiers,
    pub window_title: String,
    pub fullscreen: bool,
    /* private fields */
}

The Context stores all UI state. A user of the library shouldn’t have to interact with it directly.

Fields

key_mods: KeyboardModifiers

Keyboard modifiers state.

window_title: String

The current title of the window

fullscreen: bool

Are we fullscreen?

Implementations

impl Context

pub fn new() -> Self

pub fn update( &mut self, view: &impl View, vger: &mut Vger, access_nodes: &mut Vec<(NodeId, Node)>, window_size: Size2D<f32, WorldSpace>, ) -> bool

Call this after the event queue is cleared.

pub fn render( &mut self, render_info: RenderInfo<'_>, view: &impl View, vger: &mut Vger, window_size: Size2D<f32, WorldSpace>, scale: f32, )

Redraw the UI using wgpu.

pub fn process(&mut self, view: &impl View, event: &Event)

Process a UI event.

pub fn commands(&mut self, view: &impl View, cmds: &mut Vec<CommandInfo>)

Get menu commands.

pub fn get<S>(&self, id: StateHandle<S>) -> &S

where S: 'static,

pub fn get_mut<S>(&mut self, id: StateHandle<S>) -> &mut S

where S: 'static,
